Smart homes are homes equipped with technology that provides the occupants with comprehensive information about the state of their home and allow them to control all connected devices, including remotely.

This is not the correct answer. With Phishing an attacker tries to collect user personal data (such as passwords and credit card numbers) by means of fake apps, fake SMS, or fake email messages that seem genuine. The correct answer among those provided is privacy invasions are possible, as smart homes may collect data about people living in the house and this data could be used for instance by third parties who are the provider of smart functionalities. Such data could be, for example, details of the behaviour of people in the home, consumer activity, presence or absence, health, preferences and habits.

This answer is partially correct. Indeed, some smart home devices may have their own email accounts (this is common for web-connected printers) and this can be exploited to send spam or infected with malware messages to these devices. However, this is a general threat for any computer handling e-mail accounts. The most correct answer in this scenario is that privacy invasions are possible, as smart homes may collect data about people living in the house and this data could be used for instance by third parties who are the provider of smart functionalities. Such data could be, for example, details of the behaviour of people in the home, consumer activity, presence or absence, health, preferences and habits.
